CALENDAR.

Application filed March 21, 1923. Serial No. 626,522.

To all whom it may concern:

Be it known that I, LOUIS Bnuirownn, a citizen of the United States, residing at Port Richmond, Staten Island, New York, have invented new and useful Improvements in Calendars, of which the following is a specification.

This invention relates to a calendar, and more particularly to a calendar which may be used perpetually.

One of the objects of this invention is to produce such a calendar which shall be simple in construction, and yet durable.

,Other and further objects will appear from the more detailed description set forth below in which connection there is shown by Way of illustration in the drawing in Fig. 1, a plan view of the preferred form of my invention partially in section; in Fig. 2, a detail of the larger disc: in Fig. 3, a detail of the smaller disc; and in Fig. 4-, a view showing the relation of the various parts of the device.

It will thus be form, there are discs, associated seen that in its preferred preferably two revolving so that they maybe per Considering in greater detail the device illustrated in its preferred construction, there are shown two members 1 and 2 forming respectively a face member and a back. These members are preferably cut away at 3 and 4 as shown to allow the larger disc to be thumbed, so that it may be easily revolved; 'lheface memher is preferably formed by the seven legs 5, 5, joined by an uncut center 5 the cut away portions being arranged symmetrially. Each of these spaces is preferably In rked as illustrated to represent one day of lhe week. The larger disc 6 lies adjacent the back member 2 and is large enough in diameter to extend just beyond the cut away The outer face 7 of this larger disc 6 is also divided into seven portions arranged to seat within the seven out away portions of the face member, when the parts are assembled. Each till of these heptagonal portions is divided into five smaller areas as illustrated at 8, and these small areas are numbered as follows: Starting at the small areas (the upper left area in any chosen portion) is numbered 1, and the corresponding upper left areas of each succeeding heptagonal por tion, proceeding to count in a clockwise direction, is numbered successively from 2 up tion 5' of the face member 1.

' radial space name of themonth the order of to 7. The heptagonal portion chosen at the start, will then be reached when the upper right area will be numbered This munbering' is continued as directed above, proceeding always in-a clockwise direction until the number 31 is used. it will then be noted that the seven hep'agcnal portions are divided into three groups containing five numerals, and four groups containing four numerals each. The central portion of this disc 6 is left unoccupied, but at the very center there is a perforation 9 to receive the pin or other joint about which the disc will revolve.

In an analogous manner, a second, but smaller disc 10 is provided which covers the unoccupied portion of. the disc ti, and is in turn just large enough to extend beyond or to disappear within the uncut central por- This smaller disc is divided radially into twelve portions, 11, 1-1, each of these twelve portions being further subdivided into three smaller spaces by means of the concentric circles 12. In one of each ofthese radial spaces there is placed the names of the twelve months proceeding in a counter clockwise direction, each also carrying together with the the month, and the number of davs in the month.

The central uncut portion 5 of the face 1 is cut away as shown at 13 to uncover one centrically upon the larger disc 6, and then covering all with the face 1. A pin or other assembling; device 15 is then inserted centrally through the assembled members and bent back as at 16 to remain in position. Pins or clips or other means 17, 1? ma be further used to bind the face 1 to the ack member 2 in order to make the device ri id.

In use, the device is easily set and nee be changed but once a month. The disc 10 is revolved until the opening 13 uncovers the present month. The disc 6 is then revolved until the proper numeral. representing the day of the month falls within the proper space representing the day of the week. When thus set, the calendar will show with out manipulation the day of the month for the month set. Since, furthermore, each lllll radial portion 11 shows the number of days in each. month the device shows when the discs must be advanced for each month. The device'may accordingly readily set 'as desired. V From the description set forth it will be I apparent that various changes may be made by those skilled in the art in thesiz'e, shape,"

dimensions, arrangement, or other de'tiiils of my device withoiit departing'from the spirit or scope of my iny'ention. I

NoW, then, hemng, set forth my nventionfl claim:

A calendar comprising in-combination, a

disc divided radially into seven poreion's numbered to represent the days of the nionth and arranged in Weekly groups, a -secon disc-concentrically placed on said first disc twelve portions t o-presenb the months of the year, and a cover member cut away. to un- .coverone radiel 'monthly portion of the.

second diso, and further cut away to uncover each of the seven Weekly grou'ps of the first disc, the parts being assembled to allow each M the monthly radial portions 'to besuccese and adjacent thereto, divided radially into sively? uncovered, and .to allow rotational J movement; ofihe first disc.
